We maintain an employee benefit plan under Section 401(k) of the Internal Revenue Code.  The plan allows employees to make contributions and we may, but are not obligated to, match a portion of the employee’s contribution with our common stock, up to a defined maximum.  We also pay certain expenses related to maintaining the plan.  We recorded expenses related to our 401(k) plan of $124,000, $125,000, and $104,000 during 2015, 2014 and 2013, respectively.
